Friends App Using Rails

This is a simple Ruby on Rails application that helps manage a list of friends. The app includes authentication using Devise and allows you to store and manage personal information such as first name, last name, email, and phone number.

Requirements

• Ruby 3.3.7
• Rails 8.0.1

System Dependencies

Make sure you have the following installed on your system:

• Ruby (version 3.3.7 or higher)
• Rails (version 8.0.1 or higher)
• A supported database (e.g., PostgreSQL, MySQL, SQLite)

Getting Started

Follow the steps below to get the application up and running on your local machine.

1. Install Required Gems

Run the following command to install the required dependencies:

bundle install

2. Generate the Home Controller

Create a home controller with an index action:

rails g controller home index

3. Generate the Friend Scaffold

This will create a model, controller, and views for managing friends:

rails g scaffold Friend first_name:string last_name:string email:string:uniq phone:string:uniq

4. Add Devise Gem for Authentication

Add devise to your Gemfile:

gem 'devise'

Then install the gem:

bundle install

5. Install Devise

Run the following command to install Devise:

rails g devise:install

Follow the instructions shown in the terminal, which include:

• Adding Devise configuration to config/environments/development.rb
• Setting the root path to home#index

root "home#index"

6. Generate Devise Views

To customize the views for Devise, run the following command:

rails g devise:views

7. Set Up the Database

Run the following command to create the database and apply migrations:

rails db:migrate

8. Generate the User Model

Now, generate the Devise user model:

rails g devise user

9. Add user_id to Friends Table

Create a migration to add the user_id column to the friends table:

rails g migration AddUserIdToFriends user_id:integer:index

Then run the migration:

rails db:migrate

10. Install and Update Bundles

Make sure all gems are installed and up to date by running:

bundle install
bundle update

11. Start the Rails Server

Finally, start the Rails server:

rails s

You can now visit the application in your browser at http://localhost:3000.

Now, you have a working Rails application with authentication (via Devise) and basic CRUD functionality for managing friends!
